In 1987 an Australian sailor, Ian Kiernan, was competing in a round-the-world sailing race and he was shocked by the huge amount of rubbish which was polluting the world’s oceans. There was plastic waste floating on the sea everywhere and he decided to do something about it.

When he returned home to Sydney in the same year, he organised a special event called Clean up Sydney Harbour Day. Over 40,000 volunteers cleared away old cars, glass bottles and plastic of all kinds. It was so successful that he started Clean up Australia in 1990, and then three years later, the Clean up the World (CUW) project was founded. CUW is a campaign that inspires and encourages people worldwide to clean up and protect their environment. The organisation’s main annual event is Clean up the World weekend in September each year. During the weekend, over 600 groups from every continent clear waste from beaches, river banks and streets.

Around 35 million people in 120 countries now participate in the project, making it one of the largest community-based environmental campaigns in the world. Volunteers do things like collecting and recycling waste, planting trees, organising exhibitions and competitions and educational events. Today many volunteers continue their activities all year round.

If you want to organise a CUW event in your community, there are a lot of ideas for activities on the website and you can read about other people’s activities. For example, volunteer divers collected underwater rubbish from the Red Sea while hundreds of local volunteers and tourists cleaned up the beaches. The divers have continued their activities and they have re-introduced coral to the cleaned-up areas. In Kenya, 200 students planted trees while 300 volunteers collected eight tonnes of waste. The waste was sold for recycling and the money was given to the community to help build schools.
